To all whom it may concern Be it known that i, lninir lli. Buizen, a citizen of the United States, residing at Minerva, in the county of Starlndtate of Ohio, have invented certain new and useful improvements in `Wa gon-.Brake-rctnat ing lifechanisin, and i do hereby declare the following to be a fiill, clear, and exact description of the invention, such as will en.- able others skilled in the art to which it appertains to make and use the same.

This invention relates to wagon brakes, and it more particularly rel-at to an iinproved form of bralrevactuating mechanism adapted to be employed in connection with hay frames, etc.

An object of the invention is to provide an improved and thoroughly practical and eflicient brake-actuating mechanism in com' binationfwith the front standard or yoke of a hay frame.

Another obj ect of the invention is to provide an improved mechanism of tn is character which is built up principally from ordinary mercantile stock of pipe and pige couplings, so as to reduce the cost of mannfacture, and at the saine time to provide a strong, rigid, durable and thoroughly efficient device of this character, at a moderate cost.

Gther objects and advantages may be recited liereinafter and in the claim.

In the accompanying drawings, which supplement this specilicaion: Figure l is an elevation view of the front standard or yoke of a hay frame constructed in accor-tb ance with my invention and including my improved brake-actuating mechanism. l? 2 is a vertical sectional view on the line 2 2 of Fig. l. Fig. 3 is a hori.f/.ontaT sectional view on the line 3-3 of Fig. l, and Fig. 4

is a perspective view of one ofthe tivo counterpart castings which constitute the gear casing.

Referring to these drawings, in which similar reference characters correspond with similar part-s, throughout the several views, the body or base of the structure consists of the pipe sections 5 and 6, two 'lcouplings 7, a sleeve connection .or coupling 8, and the gear casing 9. This gear casing comprises two counterpart castings, such as illustrated in Fig. 4, each being provided with two oppositely extending semi-cylindrical bosses or projections l0, so that when the counterpart castinos are fitted together,

the respective bosses 10 thereof unite to form two oppositely extending threaded cylinders or pipe connections which engage with the couplings T and S respectively. A brakeactnating axle 11 entends into the casing through one of the elements 5 and one of the connections 7, and carries a worm gear wheel l2 on its inner end portion, said worm gear wheel being provided with oppositely disposed bosses lf3, which constitute journals which have their bearings in the opposite ends of s tions is provided with an aperture la, in vertical alineinent and constituting bearii gs for a vertical rod or crank shaft l5 having a crank handle l5 on its upper end. A worm l? is secured on the lower end of the rod i5, and is seated between the upper and lower sections of the casing 9, being in mesh with the gear wheel l5.

lxtendlng upward from tne 'connect ons 'i' are a pair of yoke elements or subs'antially vertical pipe sections i8 having their upper ends connected by means of a pipe section i9 and two L-connections Any suitable form of bearing element 2l is mounted on the pipe section i9, and the rod l5 journaled therein. rlllie pipe section if.) is meierably provided with right-hand and left-hand threads, while the 'iL-connections 20 are correspondingly threaded, so that said pipe section 19 may be screwed into both of said l-coiinections at the same time.

ri bolt or other suitable brace element is secured to the pipe sections 18 below nd substantially parallel with the section 9, so that a tie-pole (not shown) may be inserted either under and in Contact with The rotatable shaft or axle ll. may be connected in any suitable way with any iisual or preferred bralre mechanism for actuating the latter.

ifi-oni the foregoing, it will be seen that when a hay frame is equipped with my improved brake-actuating mechanism, when said frame is loaded, the driver may sit upon the load adjacent to the cranlr lever 1G and regulate the brake to suit the attending circumstances.

lt will be seen that l have provided a bialrezictiiati1ig mechanism of this character which is fully capable of attaining the foregoing objects in a thoroughly practical and etiicient manner.

the casing. flach of the easing' ioo` I do not limit my invention to the exact details of construction, combination and arrangement of parts, as herewith illustrated and described, but my invention may only be limited by a reasonable interpretation or the claim.

I claim:

A power transmission mechanism comprising ay gear casing` including two sections, each section having oppositeiy extending semi-cylindrical and externally threaded members, a support, internally threaded sleeves carried thereby and embracing the semi-cylindrical members of the casing sections, a transverse shaft in the casing and extending into the support, each of the cas-4 n testimony whereof, I aiix my signa-V ture, in the presence of two Witnesses.
